<div><div class="section"><h4 class="sectiontitle">Symptom</h4><p>When the SAN transmission mode is used for backing up a VMware VM, the VMware backup job fails and the system displays a message indicating that the VM backup progress cannot be obtained.</p>
</div>
<div class="section"><h4 class="sectiontitle">Possible Causes</h4><p>The name of a protected VM or disk contains the special character @.</p>
</div>
<div class="section"><h4 class="sectiontitle">Troubleshooting</h4><ol><li><span>Check whether the VM name or virtual disk name contains the special character @.</span><p><ol type="a"><li>Use a client or browser to log in to the ESXi host or vCenter Server.</li><li>Check whether the names of the VMDK files of the corresponding VM in the datastore and their parent folders contain the at sign (@).<ul><li>If yes, go to <a href="#EN-US_TOPIC_0000002164654254__li19710311824">2</a> to change the VM name.</li><li>If no, contact technical support engineers.</li></ul>
